  1. Hey guys just seeing if anyone has any ideas about what I should check next. my car has a pretty bad misfire under load (basically as soon as I hit boost it misfires and carries on). I’ve got brand new spark plugs and genuine coils. Intercooler has been cleaned so there shouldn’t be any oil residue in there from my old turbo sh*tting itself. The car is 480kw on e85 so it’s very noticeable when you hit boost and it misfires. When I replaced spark plugs and coils it fixed the issue for about 50km then it came back, I’m thinking of checking spark plug gap next? Just seeing if anyone has had the same issue. ive read other threads with this problem but nothing really helped
  2. Hey guys new to the forum, just bought myself an 2011 fg xr6t with 120k on the clock and barely made it home before the engine light came on. Put a diagnostic tool on it and the error code says P0305 cylinder 5 missfire, I am assuming its a coil, is this a common problem? Seems to be really bad at lower revs. Got to be a record owned the car for about and hour :( Thanks
  3. Hi guys, After filtering through all the misfire related topics and find very few threads with actual resolutions I thought I'd start a new one. Basically my 09 FG G6e turbo started misfiring at WOT when at the strip the other night. 400rwkw running E85 to give an idea of mod level. The thing had done it before, when it did I took it back to the tuner where it got a service and retune and came out happy as. Has been running sweet for about 6 months now but the problem has returned and is far worse. Essentially when I am on hard boost it sounds like it has a very bad misfire and no power obviously. Originally it was just under WOT but on the way back from the track it got worse, occasionally misfiring while.cruising at 100kph and but the time I got home (100km later) struggling to idle without misfiring. With slight throttle it runs smooth as so I'm thinking it has to do with ignition as the extra voltage with slight throttle will help spark but as soon as any fuel or boost is dumped into the engine it misfires again. I am yet to talk to my tuner (will today) but will update this post, through to resolution so hopefully it can help out the next victim. Keen to here any ideas or similar stories. Cheers, Joel
  4. Hi guys, I have a bone stock manual 2005 XR6 Turbo Ute, done 97000ks. I'm occasionally getting a "misfire" of sorts when under load in 3rd or 4th gear. It doesn't happen all the time, but when it does, its at about ~4000rpm in 3rd or 4th gear only, happens whether I'm WOT or just cruising up the rpms, seems to be when it's at full boost. When it occurs, the rpms drop instantly back to about 2000-3000 and I have no input with the accelerator. If I try to accelerate it just stays at about 2000ish rpm and the engine sounds like its "out of sync" for lack of a better term. I either have to turn the car off and on again, or put it in neutral (still moving) blip the accelerator a couple times, put in back in a gear and the engine just "gets back in sync" and starts revving normally again. I've searched the forums and have tried a few suggestions. I've had my mechanic replace the intake manifold gasket, spark plugs and coils but it has made no difference. It's hard for a mechanic to diagnose because they test drive it and it's fine or they can't get it to do it so they can only suggest parts to change based off the problem I'm describing. If anyone has any suggestions please let me know. Cheers.
  5. hey all, got a mk1 fg xr6t. got tuned to 390rwkw on 98, all the supporting mods for it. car was running nicely right up until a week and a bit later, the pcm stopped sending signal to coil 5. swapped coils around and the coil from cylinder 5 worked in other cylinders. new ecu and new coils (genuine ford not aftermarket junk), ecu calibration from ford and some $$$ later, it's still misfiring. ran vac tests, checked injectors and adaptors. only thing that remains the same is harness, which hasn't been touched in any way so unsure of how it could have made the first pcm driver fail. fingers crossed the second computer isn't f#@ked. has anyone else had these issues and if so how were they resolved? my tuner isn't a ford specialist but has tuned a good handful of high power barras without fault. my fg and another customers (his is mk 2) got pretty well all the same parts and got work done at the same time have the same fault. (both copped code p1358) but my car was perfect for a week and his car didn't even make it to final stages of the tune. my tuner and another local-ish tuner have beef which I don't want to become a part of so no jumping ship or naming them. any help would be appreciated because it's been near a month and I miss driving my car and feeding commodores
  6. Hi guys my 2004 ba xr6turbo misfire over 3000 rpm, I change spark plugs and put brand new aftermarket coil pack, but my car still misfire, my mechanic says put genuine(bosh) coil packs? Any idea pls?? :((
  7. Ok I’ve read page after page after page.... heres where it starts.... bought a ba xr6 turbo Automatic and it came with a x3 flash device that has custom tunes, base 4-5 psi - 8psi - 10psi. Car drives great no weird noises or anything of the like. The problem I’m having is to do with a overboost/limiter issue. This is the 10psi tune. Car accelerates great but once it hits the 10psi mark it either goes to 12psi or it hits 9-10 and it’s like a rev limit and the exhaust makes an almost ‘flame’ sound? And the boost gauge flickers up and down 1psi. Mostly this happens with WOT. Especially does it when just in Drive and going WOT, not so bad in sport mode because I can shift before it gets to the almost misfire stage and goes weird. Most times regardless of in drive or sports mode it’s around 4000rpm. Sometimes though in drive and sports mode it will rev out and hit boost perfectly and have no issues but it’s very short lived and then it’s back to ‘missing’ 2 minutes later. Now when I put it back to stock it hits 5 psi steady as can be at WOT but as it hits 5000-5500rpm it makes the same weird flame limiter noise. Heres what I’ve tried. •New plugs gapped to 7.5 •New boost control solenoid •Clean throttle body •Tighten all hoses that I can access •Run turbo hose straight to wastegate (hits 5-6psi and goes great •Disconnect battery for 10 minutes and then drive WOT New coil packs will be here by the end of the week as there about the last thing I can think of that I can do myself, there still originals and car has done 170,000ks. So if anyone can help me that would be AWESOME! I’ve read so many threads that seem to be my problem and they either never come back with the solution or I’ve tried what they’ve done to no avail.
  8. Hi all, reasonably new to this group but having dramas with my fg. Car is an fg with a built 698 atomic engine with about 50000km on it. It started off dropping number 5 cylinder with a fault code suggesting it was coils, changed coils same problem. Got a new computer and loaded myHi all, reasonably new to this group but having dramas with my fg. Car is an fg with a built 698 atomic engine with about 50000km on it. It started off dropping number 5 cylinder with a fault code suggesting it was coils, changed coils same problem. Got a new computer and loaded my files onto it and it was fixed... For about half an hour then dropped 5 again. After that You could start it up and it would run on sequential injection for the first 10 seconds then immediately drop number 5 again. So we decided maybe we would do the imjector harness. So we replaced that and got another new computer and loaded files onto it. At last she ran on all 6, even dynoed it and all again. Then without warning its dropped number 1 cylinder, with fault codes pointing to coil windings, swapped coils but number one has nothing. Doesn't even run on 6 when first started. That brings us to today. Starts and runs on 5 cylinders. I'm at breaking point and any help would be appreciated Cheers
